Yes. Modern pianos have three pedals, from left to right, the soft pedal (or una corda), the sostenuto pedal (mainly found in American-made grands), and the sustaining pedal (or damper pedal). All of them change the instrument's sound in various ways, depending on the pedal and the piano.

The soft pedal, the one at the left, is designed to make the sound softer and lower the volume, but it also modifies timbre and color of the tone.

The middle pedal, the sostenuto pedal, is not so common, and it's the last pedal to be added to the modern grand. This pedal is made to sustain selected notes while other notes remain unaffected.

The pedal at the right, the sustaining pedal, raises all the dampers off the strings so that they can continue to vibrate and sound after a note on the keyboard has been released. It adds much expressivity to piano music, allowing notes to resonate, and certain harmonies and notes to be connected together. This is the most used pedal.

The middle pedal on a grand piano is called the "sostenuto" pedal. The left-most pedal is the "una corda" or "soft" pedal, and the right-most pedal is the "damper" pedal. The sostenuto pedal on a grand piano keeps the dampers up for the keys that are depressed at the time the pedal is depressed, t…hus allowing the sound of these strings to continue after the keys are released. You can continue to play the rest of the keys, even using the damper pedal, independently of the action of the sostenuto. As long as the sostenuto is depressed, those notes will continue to sound. So the pedal has to be used correctly, or some notes you don't intend to continue sounding will anyway. On upright pianos, however, the middle pedal, if one exists, is typically a practice pedal, mute pedal or celeste pedal, which places a piece of felt between the hammers and the strings. This is intended to be used for quiet practicing, and it is rarely if ever used for musical purposes. Some uprights have a sort of mock-sostenuto pedal, which sustains only the lower strings. This is of fairly limited use. In some older uprights, the middle pedal is merely a duplicate of the left (soft) pedal. As a true sostenuto pedal requires a fairly complex mechanism, only very few uprights have one. However, since it is used very infrequently, it is rarely missed by most players. The sostenuto pedal didn't become popular until 1874, when Steinway introduced it. Obviously, earlier composers did not use it! Even Debussy (1862 - 1918) did not have a piano with a sostenuto pedal. Many modern concert pianists avoid the sostenuto pedal entirely. (MORE)

Using oil is not recommended in a piano. It attracts dirt and grime. Call a piano tech or have them look at it when they tune it. It won't cost much have it fixed properly. .

You will need to access the mechanical linkings in the bottom mo…st part of the piano. To do this, you will need to open the lower panel (usually a knob or metal type spring holds it in place) which will expose the mechanical linkings for the 3 pedals..
Apply a light grade oil (sewing machine or hair clipper oil) to the pivot points nearest the actual pedals themselves. Work the pedals to make sure the oil penetrates the moving joints. Wipe up any excess oil that may have dripped onto the inside floor of the piano..
Replace the lower panel (there are a couple guide pins that line up with holes in the bottom of the panel and secure in place..
There is also a spring and connection behind the action that might be causing a little squeaking noise, too. To access this, remove the front panel that exposes the action (hammers, strings, etc). At either end is a know, unscrew this and remove, and gently tilt the action toward you. Look down between the strings and the action, and there should be a connection joint and/or spring. Place a few drops of the previously mentioned lubricating oil at the rod connection joint being extremely careful not to spill any on the rest of the mecanisms or hammers. Gently tilt the action back into place and again secure with the knobs. (MORE)

Leftmost pedal: Pianissimo: moves the hammers closer to the strings that produce a softer sound. On grand pianos (horizontal instrument) the entire keyboard moves to the right allowing the hammers to hit only one string instead of 3 strings as they n…ormally would. Middle pedal: Different manufacturers perform different tasks: - some sustain the lower notes only, like from tenor c downwards, - others (Young Chang for instance) drop a piece of felt between the hammers and the strings, producing a very subdued tone - used more for practicing as opposed to performance. Rightmost pedal: Sustain Pedal. Not necessarily a "loud" pedal. Loudness is accomplished by how much weight one uses when playing the piano keys. A heavier touch produces a louder sound - one can hold the sustain pedal down and produce very soft music, too. When this pedal is depressed, the dampers are pulled away from all the strings. As long as this pedal is used, all strings will continue to resonate until they stop vibrating. (MORE)

The piano has 88 keys, each one playing a different note, or sound pitch. Pressing a key on the keyboard causes a felt-covered hammer to strike steel strings. The hammers then rebound and the strings vibrate. These vibrations are transmitted through a bridge to a sound board that couples the acousti…c energy into the air. (MORE)

When a key is depressed, it acts as a lever that pushes a lever that pushes a lever that pushes a lever in a "domino-effect" way that transfers the downward motion of the key to the forward or upwards motion of the hammer, which strikes the string(s).

The right pedal on a piano is called the damper pedal. When you press down on the damper pedal, you raise (or lift) the felt dampers off the strings. Any notes that are being played at the time the damper pedal is depressed will continue to resonate. Using this pedal raises the dampers for the ent…ire piano regardless of what notes have been played, so a skillful pianist can make use of the added resonance you get when all strings are open to vibrate whether or not their note has been played. The danger for most young piano students is to badly over-use the pedal (because it may sound to the student like playing the pedal is adding volume or substance to the sound when in fact it is only creating a muddy sound) or not to use it at all, making lines sound choppy. It is probably best although not necessarily easiest for students to learn early on to create lines as much as possible by working out fingering , so that the pedal is not relied upon to compensate for lazy technique. Then the student can learn to use the pedal for much more beautiful effects. (MORE)

What do pedals on a piano do?.
The three pedals that have become more or less standard on the modern piano are the following. From left to right: una corda, sostenuto and damper. The damper pedal (also the sustaining pedal or loud pedal) is the most frequently used. It is placed as the rightmost pe…dal in the group. Every string on the piano, except the top two octaves, is equipped with a damper, which is a padded device that prevents the string from vibrating. The damper is raised off the string whenever the key for that note is pressed. When the damper pedal is pressed, all the dampers on the piano are lifted at once, so that every string can vibrate. This serves two purposes. First, it assists the pianist in producing a legato (playing smoothly connected notes) in passages where no fingering is available to make this otherwise possible. Second, raising the damper pedal causes all the strings to vibrate sympathetically with whichever notes are being played, which greatly enriches the piano's tone. The una corda pedal (also the soft pedal) is placed leftmost in the row of pedals. On a grand piano this pedal shifts the whole action to one side, slightly to the right, so that hammers that normally strike all three of the strings for a note strike only two of them. This softens the note and modifies its tone quality. On many upright pianos, the pedal operates a mechanism which moves the hammers' resting position closer to the strings. This reduces the volume as the hammers have less distance to travel, but this does not change tone quality in the way the una corda pedal does on a grand piano. However when this pedal is depressed on the vertical, it changes the action creating what is called lost motion, that is the jack is now further from the hammer butt, and now has to travel further to engage the hammer. This lost motion changes the touch and feel of the playing action, and as a result many pianists never use the soft pedal on a vertical. Since the grand piano soft pedal simply shifts the action sideways, it does not change the touch and feel of the action, another advantage grand pianos have over vertical pianos. The sostenuto pedal (also the middle pedal) keeps raised any damper that was raised at the moment the pedal is depressed. This makes it possible to sustain some notes (by depressing the sostenuto pedal before notes to be sustained are released) while the player's hands are free to play other notes. This can be useful for musical passages with pedal points and other tricky or impossible situations. The sostenuto pedal was the last of the three pedals to be added to the standard piano, and to this day, many pianos are not equipped with a sostenuto pedal. Almost all modern grand pianos have a sostenuto pedal, while nearly all upright pianos do not. Some upright pianos have a celeste pedal (practice pedal) in place of the sostenuto. This pedal, which can usually be locked in place by depressing it and pushing it to one side, drops a strip of felt between the hammers and the strings so that all the notes are greatly muted-- a handy feature for those who wish to practice without disturbing everyone else in the vicinity. http://en.wikipedia.org/wiki/Piano#Pedals (MORE)

Often mistakenly called the 'loud' pedal, it is anything but. The right pedal, when depressed, causes the dampers on the strings to move away so that when you play a succession of notes, each note does not stop sounding when you play the next one. So this pedal is called the 'sustaining' pedal becau…se, if used wisely, it can create a smoother performance when one is needed. However, too many poor pianists hold down this pedal unnecessarily to create a 'smooth' effect, but all they achieve is a mishmash of horrible sound as one chord is sustained into another. So if you are learning the piano, use it wisely!.
Incidentally, pianos have at least one or sometimes two other pedals. The leftmost pedal on a grand piano has the effect of moving the keyboard slightly so that the hammers hit only one string per note, instead of the usual two or three. This has the effect of making the sound much quieter and softer. When you see 'una corda' written in piano music this means 'one string' and is an instruction to depress the left pedal during that passage of music. In upright pianos, there is also a 'una corda' pedal, but in uprights it has the effect of moving the hammers nearer the strings (or in cheap pianos of moving a thin piece of felt between the hammers and strings) which has a similar effect. On some pianos, there is a third, middle pedal. In cheap pianos, this moves a thick piece of felt between the hammers and strings making the sound very soft and woolly. This is used for practicing passages that you don't want to play loudly yet as they may be full of mistakes (so as not to disturb the neighbors!)! In jigher-priced pianos, this middle pedal has a sustaining effect that is not like the right-hand pedal. If you play a note and then press the middle pedal, this one note is sustained when all subsequent notes are not. This is useful if you want, say, a chord to sustain throughout another passage and you do not have enough fingers to hold down the chord and play the other notes as well. You could use the right-hand sustaining pedal, of course, but this would have the effect of sustaining the chord and all the notes of the subsequent passage, resulting in a messy sound. (MORE)

Oh, my goodness! Many people call it the loud pedal. The right pedal is the damper pedal, and it gets the unfortunate nickname 'loud pedal' because with it you can open all the piano strings at the same time. The damper pedal's function is not to make anything louder than anything else; in fact volu…me is a function of how you use your body arms and wrists. The damper pedal can help the pianist create smoothe and beautiful legato and legatissimo lines, and there are things that can be done with it that would be somewhat difficult to describe briefly.

Normal keyboards make clickity-click noises (unless there is a sort of padding, in which a rubber-click sound is made). The pitch of a click does not change from keys next to each other, in the case of a normal-format QWERTY keyboard..

The left hand pedal on a piano is the soft pedal, it softens the sound (makes it quieter) by pressing the dampers (pads that rest against the strings to stop the sound from ringing) harder against the strings. The right pedal which is called the damper pedal releases the dampers from the strings, ca…using the notes to be sustained. The middle pedal is called a "Sostenuto Pedal" and it removes the dampers from the only the notes that are played when the pedal is depressed, therefore sustaining some and not others. (MORE)

If you want a true piano sound, go with a Yamaha. They are known for their piano voices. The ones that are deemed to truly mimic the sound and touch of the the concert grand piano are the Yamaha AvantGrand pianos model N3 and N2. Korg and Roland are well known for synthesizers.

A piano peal stool, or pedal extender, is a platform that essentially raises up the pedals so that those who can't reach them can now do so. It is basically a platform with usually 2 pedals on it that gets placed over the real piaono pedals. When the piano player steps on the pedals that are on the …platform, the real piano pedals are engaged by the platform pedals. To see how they work, visit the related link below. (MORE)

it works by decreasing the distance between the hammers and the strings. So since the hammer has less room to travel when the soft pedal is pressed it can not build up as much speed therefore can not strike the string as hard which results in softer volume.

The left pedal is the unachorda or soft pedal. In a grand, it shifts the keyboard to miss one string tomake the sound softer. In an upright, it moves the hammers closer but that is not very effective. The middle pedal is the sustenuto but is only effective in that capacity on grand pianos and some …old espensive uprights. In some modern uprights, the middle pedal lowers a piece of felt cloth between the hammers and strings to make it play soft and is called the Practice pedal. The right pedal is the loud or expression pedal. The controls the dampers that allow the strings to continue to ring. (MORE)

While the left pedal on virtually any acoustic piano would be called the una corda pedal, the name comes closest to being true for pianos built in the style of the grand piano, with a vertical soundboard. On a grand, when the una corda is depressed, the entire keyboard is shifted slightly to the rig…ht. The keyboard itself moves! This is because the entire action is built in such a fashion that if you want the hammers to strike the wires in a different alignment, then the entire action has to move to accommodate the movement of the hammers. This is done so that (theoretically) the hammers that normally strike three wires, for notes in the piano's mid-range, are striking one wire instead. However, I believe this is not really what happens. Using the una corda does produce a different sound but the hammers don't move enough to really isolate one wire for striking. What happens is that the slight movement of the hammers causes the hammers to make contact with the wires at places on the hammers that have not been hardened by normal playing. The result is that a slightly softer felt is causing the string to vibrate, producing a slightly softer and rounder tone. (MORE)

2 on a piano and i think 11 on an organ. .
Answer .
On a piano, normally 2 or 3. One is 'sustain' which lets the notes keep sounding when you release the keys. One is 'soft' which dampens the volume of the playing. The third one is optional, it is a 'practice' pedal which mutes the sound even more…. .

Pedals for the piano began life as pedals for the harpsichord. Very few harpsichords were outfitted with pedals because the purpose of the pedals was to change registration quickly and easily on the harpsichord, without having to lift the hands from the keys to do the same thing. Mostly, it was the …English who dabbled in applying pedals to the harpsichord. As a result, they were also the first to add pedals to pianos. Before that, the earliest pianos made had no pedals at all because they were considered to be harpsichords with loud and soft (in Italian, "Gravicembalo col Forte e Piano") When the addition of stops on the forte-pianos were created to change the sound, it involved manually shifting the keyboard or pulling or pushing a handstop to effect the change. Later, the Austrian and German fortepiano makers invented the knee lever to raise and lower the dampers. The English pianoforte makers were applying pedals to do the same thing about the same time. By 1815, pedals were standard equipment on almost every piano. In Vienna from 1828- 1845, piano makers would customarily have as many as 5 - 7 pedals on a piano. These pedals activated bells, drums, snare effects and muffled effects, as well as the usual damper lifting and keyboard moving actions. In England, piano makers limited themselves for the most part to only 2 or 3 pedals. These differences were largely dictated by the peculiar nature of the action designs for the pianos from these different areas of Europe. (MORE)

The far left pedal on some pianos when pressed, will sustain the lower half of the piano. This ideal for holding down a chord for a long time or when both hands are needed higher up on the piano. It's rarely used. However on some pianos, it's used to lightly soften the sound of the piano. The midd…le pedal is the practice pedal. It dramatically softens the sound of the piano. The far right pedal is the sustain pedal. It lifts the dampers on the piano so that every note that is hit, keeps ringing until the pedal is released, dropping the dampers and stopping the sound. A side note to this is that the functions of each pedal varies from piano to piano, although, the far right sustain pedal is the same on ever piano. (MORE)

It helps greatly if you have a pedal wrench - it's custom made to be thin enough to fit in the small axle space between your pedals and the crank arms, and long enough to give you the torque required to unscrew them. I'd recommend anything from Park Tools, I picked mine up for about $15. Secure yo…ur bike frame, either in a bike stand, by propping it against a wall, or by flipping it upsidedown and having it rest on the saddle and handlebars. It does need to be relatively sturdy or your bike will simply roll away or fall over when you try to unscrew the pedals. Don't forget that the left pedal will be threaded backwards to prevent it from unscrewing while you pedal. This means you'll have to turn it to the right (clockwise) to loosen it, going against the usual 'righty tighty' method. Hold the wrench at an acute angle with the crank arm; this will allow you to get more leverage and turn until the pedals are loose. Then remove the right pedal normally; turning the axle to the left (counter-clockwise). Then replace with your new pedals. Remember to grease the threads slightly to reduce wearing, and don't overtighten them; you can usually screw them in by hand, with just a few turns needed by wrench to secure them. Tighten the right pedal by turning the wrench clockwise, and tighten the left pedal by turning counter-clockwise. (MORE)

A piano produces sound by using hammers to hit a string. When a key is pressed, the damper that keeps the string silent is lifted, and the hammer that belongs to it hits the corresponding string, causing the vibrations we know as sound. The higher notes are produced using thin strings. The lower the… tone, the thicker the string. The damper pedal helps the pianist produce a quieter sound, and the sustain pedal helps the pianist hold a note by keeping the dampers off the strings. (MORE)

yes, one is to make the piano quite if its a loud one, one is to sustain the notes (those are the most common ones) the third one is if you want a chord to be sustained, but dont want the rest of the notes to be you hold that pedal down

Yes, they do. The original 1900-1930 pianos almost all have a sustain lever you use to operate the sustain pedal function of the piano when a roll is playing. In addition, most also have the ability for the roll to automatically operate the sustain pedal when playing.

When are you referring to? When the piano was made, and beethoven and Mozart were still alive, the Pianos had a much worse tone than they do today. They were not as loud, so when you play an old piece these days and the term forte is in the piece, we do not play as loudly as we can on our pianos as …it sounded different back then. But, it is ok if it is a loud and thumpy song. And since there were note as many keys on the piano back then, the composers were composing on limited keys (MORE)

Generally the fourth pedal raises the hammers nearer the strings and reduces the touch depth. This enables the player to play very softly (and rapidly, if necessary)still employing the full tone of the instrument. It can be also used with the 'shift' pedal for even more effect. On some other b…rand pianos, (more modern ones), the 4th pedal is designed to make a honky-tonk sound. (MORE)
